First report of Monilinia fructicola on peach and nectarine in China.

This article is the first report of the occurrence of Monilinia fructicola on stone fruit in China. In 2003 and 2004, peach and nectarine fruit showing typical brown rot symptoms were found in an orchard in a suburb of Beijing, China. The pathogen was identified as Monilinia fructicola based on morphological and molecular approaches. Pathogenicity was tested by inoculating surface sterilized, mature nectarine fruit with a droplet of conidial suspension Brown rot of stone fruit is commonly caused by one of the three Monilinia species. It is still not clear which is the major causal pathogen in stone fruit in China.
